Fisheries are composed of one or more parts, each of which is entitled to receive an MSC certificate. These parts or “units” are defined by their target stock(s), fishing gear type(s) and if relevant vessel type(s), and the fishing fleets or groups of vessels.

When the term “Unit of Certification” is used for fishing units that are in assessment, it refers to the “Unit of Assessment” or “Unit of potential certification”.

About this Fishery

Patagonian toothfish – sometimes sold as Chilean seabass – is a highly prized deepwater fish that can grow over 2m long. Toothfish are slow to mature and reproduce, and populations have been severely depleted by overfishing, particularly illegal, unregulated and unreported (IUU) fishing. 

Satellite tagging studies have shown that adult toothfish do not migrate or move over large distances. This suggests that there is very little movement between this fishery, which operates around the Falkland Islands, and other toothfish fisheries.

Toothfish stocks around the Falklands are being managed at sustainable levels, with a maximum of two vessels operating in fishery. They use longlines to target toothfish, which has minimal impact on marine habitats. 

While bycatch of seabirds such as albatrosses used to be a serious problem in toothfish fisheries, statutory mitigation measures have effectively eliminated this. Managers and assessment scientists have reported that there is no evidence of recent illegal activity.
